[Olena-patches] 2293: Update line graph psite set.

* mln/core/site_set/p_line_graph.hh (mln::p_line_graph<P>): Inherit from internal::site_set_base_< site_pair<P>, p_line_graph<P> >. (mln::p_line_graph<P>::self_) (mln::p_line_graph<P>::super_): New typedefs. (mln::p_line_graph<P>::site): Remove typedef. (mln::p_line_graph<P>::element): Define as mln_site(super_). (mln::p_line_graph<P>::nsites): Set return type to unsigned. (mln::p_line_graph<P>::has): Update w.r.t. the new interface of mln::line_graph_psite. * mln/core/concept/site_set.hh (site_set_nsites_check<mln::trait::site_set::nsites::known, E>::run): Add a FIXME. --- milena/ChangeLog | 19 ++++++++++++++++++ milena/mln/core/concept/site_set.hh | 1 + milena/mln/core/site_set/p_line_graph.hh | 31 +++++++++++++++++++++-------- 3 files changed, 42 insertions(+), 9 deletions(-) diff --git a/milena/ChangeLog b/milena/ChangeLog index ae13b3c..856b341 100644 --- a/milena/ChangeLog +++ b/milena/ChangeLog @@ -1,5 +1,24 @@ 2008-09-17 Roland Levillain &lt;roland(a)lrde.epita.fr&gt; + Update line graph psite set. + + * mln/core/site_set/p_line_graph.hh (mln::p_line_graph<P>): + Inherit from + internal::site_set_base_< site_pair<P>, p_line_graph<P> >. + (mln::p_line_graph<P>::self_) + (mln::p_line_graph<P>::super_): + New typedefs. + (mln::p_line_graph<P>::site): Remove typedef. + (mln::p_line_graph<P>::element): Define as mln_site(super_). + (mln::p_line_graph<P>::nsites): Set return type to unsigned. + (mln::p_line_graph<P>::has): Update w.r.t. the new interface of + mln::line_graph_psite. + * mln/core/concept/site_set.hh + (site_set_nsites_check<mln::trait::site_set::nsites::known, E>::run): + Add a FIXME. + +2008-09-17 Roland Levillain &lt;roland(a)lrde.epita.fr&gt; + Update line graph psite. * mln/core/image/line_graph_psite.hh diff --git a/milena/mln/core/concept/site_set.hh b/milena/mln/core/concept/site_set.hh index 2e9d4b7..40b288e 100644 --- a/milena/mln/core/concept/site_set.hh +++ b/milena/mln/core/concept/site_set.hh @@ -186,6 +186,7 @@ namespace mln { static void run() { + // FIXME: Return type should be std::size_t. unsigned (E::*m)() const = & E::nsites; m = 0; } diff --git a/milena/mln/core/site_set/p_line_graph.hh b/milena/mln/core/site_set/p_line_graph.hh index 036cfef..548b9e2 100644 --- a/milena/mln/core/site_set/p_line_graph.hh +++ b/milena/mln/core/site_set/p_line_graph.hh @@ -28,6 +28,8 @@ #ifndef MLN_CORE_SITE_SET_P_LINE_GRAPH_HH # define MLN_CORE_SITE_SET_P_LINE_GRAPH_HH +# include <mln/util/site_pair.hh> + # include <mln/core/concept/point_site.hh> # include <mln/core/internal/site_set_base.hh> # include <mln/accu/bbox.hh> @@ -47,6 +49,7 @@ namespace mln { + // Forward declaration. template<typename P> struct p_line_graph; @@ -69,8 +72,11 @@ namespace mln template<typename P> struct p_line_graph - : public internal::site_set_base_< line_graph_psite<P>, p_line_graph<P> > + : public internal::site_set_base_< site_pair<P>, p_line_graph<P> > { + typedef p_line_graph<P> self_; + typedef internal::site_set_base_< site_pair<P>, self_ > super_; + typedef util::graph<P> graph; /// \brief Construct a line graph psite set from a graph of points. @@ -84,10 +90,7 @@ namespace mln /// Associated types. /// \{ /// Element associated type. - typedef P element; - - /// Site associated type. - typedef P site; + typedef mln_site(super_) element; /// Point_Site associated type. typedef line_graph_psite<P> psite; @@ -107,7 +110,9 @@ namespace mln /// line graph. /// /// Required by the mln::Point_Set concept. - std::size_t nsites() const; + /* FIXME: Return type should be std::size_t (see + mln/core/concept/site_set.hh). */ + unsigned nsites() const; /// Return The number of vertices in the graph. std::size_t nvertices() const; @@ -160,6 +165,10 @@ namespace mln bool operator==(const p_line_graph<P>& lhs, const p_line_graph<P>& rhs); + + /* FIXME: Extend the `ord' mechanism instead of this ill-defined + pseudo-order. */ + /// \brief Inclusion of a mln::p_line_graph in another one. /// /// This inclusion relation is very strict for the moment, since our @@ -189,7 +198,7 @@ namespace mln template <typename P> inline - std::size_t + unsigned p_line_graph<P>::nsites() const { return nedges(); @@ -235,9 +244,9 @@ namespace mln { return // Check whether P is compatible with this psite set. - (&p.plg() == this) && + (p.target_() == this) && // Check that the edge id of P belongs to the range of valid edge ids. - (p.id() < gr_->nedges()); + (p.is_valid()); } template <typename P> @@ -317,6 +326,10 @@ namespace mln bool operator==(const p_line_graph<P>& lhs, const p_line_graph<P>& rhs) { + /* FIXME: We should not rely on pointer equality here, as graph + will soon become shells using (shared) tracked pointers to + actual data.
